Update to v103r04 release.
byuu says:
Changelog:
- fc/apu: $4003,$4007 writes initialize duty counter to 0 instead of 7
- fc/apu: corrected duty table entries for use with decrementing duty
counter
- processor/spc700: emulated the behavior of cycle 3 of (x)+
instructions to not read I/O registers
- specifically, this prevents reads from $fd-ff from resetting the
timers, as observed on real hardware
- sfc/controller: added ControllerPort class to match Mega Drive
design
- sfc/expansion: added ExpansionPort class to match Mega Drive design
- sfc/system: removed Peripherals class
- sfc/system: changed `colorburst()` to `cpuFrequency()`; added
`apuFrequency()`
- sfc: replaced calls to `system.region == System::Region::*` with
`Region::*()`
- sfc/expansion: remove thread from scheduler when device is destroyed
- sfc/smp: `{read,write}Port` now use a separate 4x8-bit buffer instead
of underlying APU RAM [hex\_usr]

Update to v103r02 release.
byuu says:
Changelog:
- fc/apu: improved phase duty cycle emulation (mode 3 is 25% phase
inverted; counter decrements)
- md/apu: power/reset do not cancel 68K bus requests
- md/apu: 68K is not granted bus access on Z80 power/reset
- md/controller: replaced System::Peripherals with ControllerPort
concept
- md/controller: CTRL port is now read-write, maintains value across
controller changes (and soon, soft resets)
- md/psg: PSG sampling rate unintentionally modified¹
- processor/spc700: improve cycle timing of (indirect),y instructions
[Overload]
- processor/spc700: idle() cycles actually read from the program
counter; much like the 6502 [Overload]
- some of the idle() cycles should read from other addresses; this
still needs to be supported
- processor/spc700: various cleanups to instruction function naming
- processor/z80: prefix state (HL→IX,IY override) can now be
serialized
- icarus: fix install rule for certain platforms (it wasn't buggy on
FreeBSD, but was on Linux?)
¹: the clock speed of the PSG is oscillator/15. But I was setting the
sampling rate to oscillator/15/16, which was around 223KHz. I am not
sure whether the PSG should be outputting at 3MHz or 223KHz. Amazingly
... I don't really hear a difference either way `o_O` I didn't actually
mean to make this change; I just noticed it after comparing the diff
between r01 and r02. If this turns out to be wrong, set
stream = Emulator::audio.createStream(1, frequency() / 16.0);
in md/psg.cpp to revert this change.

Update to v103r01 release.
byuu says:
Changelog:
- nall/dsp: improve one pole coefficient calculations [Fatbag]
- higan/audio: reworked filters to support selection of either one
pole (first-order) or biquad (second-order) filters
- note: the design is not stable yet; so forks should not put too
much effort into synchronizing with this change yet
- fc: added first-order filters as per NESdev wiki (90hz lowpass +
440hz lowpass + 14khz highpass)
- fc: created separate NTSC-J and NTSC-U regions
- NESdev wiki says the Japanese Famicom uses a separate audio
filtering strategy, but details are fuzzy
- there's also cartridge audio output being disabled on NES units;
and differences with controllers
- this stuff will be supported in the future, just adding the
support for it now
- gba: corrected serious bugs in PSG wave channel emulation [Cydrak]
- note that if there are still bugs here, it's my fault
- md/psg,ym2612: added first-order low-pass 2840hz filter to match
VA3-VA6 Mega Drives
- md/psg: lowered volume relative to the YM2612
- using 0x1400; multiple people agreed it was the closest to the
hardware recordings against a VA6
- ms,md/psg: don't serialize the volume levels array
- md/vdp: Hblank bit acts the same during Vblank as outside of it (it
isn't always set during Vblank)
- md/vdp: return isPAL in bit 0 of control port reads
- tomoko: change command-line option separator from : to |
- [Editor's note: This change was present in the public v103,
but it's in this changelog because it was made after the v103 WIP]
- higan/all: change the 20hz high-pass filters from second-order
three-pass to first-order one-pass
- these filters are meant to remove DC bias, but I honestly can't
hear a difference with or without them
- so there's really no sense wasting CPU power with an extremely
powerful filter here
Things I did not do:
- change icarus install rule
- work on 8-bit Mega Drive SRAM
- work on Famicom or Mega Drive region detection heuristics in icarus
My long-term dream plan is to devise a special user-configurable
filtering system where you can set relative volumes and create your own
list of filters (any number of them in any order at any frequency), that
way people can make the systems sound however they want.
Right now, the sanest place to put this information is inside the
$system.sys/manifest.bml files. But that's not very user friendly, and
upgrading to new versions will lose these changes if you don't copy them
over manually. Of course, cluttering the GUI with a fancy filter editor
is probably supreme overkill for 99% of users, so maybe that's fine.

Update to v103 WIP release.
byuu says (in the WIP forum):
Changelog:
- higan: cheat codes accept = and ? separators now
- the new preferred code format is: address=value or
address=if-match?value
- the old code format of address/value and address/if-match/value
will continue to work
- higan: cheats.bml is no longer included with the base distribution
- mightymo stopped updating it in 2015, and it's not source code;
it can still be pulled in from older releases
- fc: improved PAL mode timing; use PAL APU timing tables; fix PAL
noise period table [hex\_usr]
- md: support aborting a Z80 bus wait in order to capture save states
without freezing
- note that this will violate accuracy; but in practice a slight
desync is better than an emulator deadlock
- sfc: revert DSP ENDX randomization for now (want to research it more
before deploying in an official release)
- sfc: fix Super Famicom.sys/manifest.bml APU RAM size [hex\_usr]
- tomoko: cleaned up make install rules
- hiro/cocoa: use ABGR for pixel data [Sintendo]
Note: I forgot to change the command-line and drag-and-drop separator
from : to | in this WIP. However, it is corrected in the v103 official
binary and source published on download.byuu.org. Sorry about that, I
know it makes the Git repository history more difficult. I'm not
concerned whether the : → | change is part of v103 or v103r01 in the
repository, and will leave this to your discretion, Screwtape.
I also still need to set the VDP bit to indicate PAL mode in the Mega
Drive core. This is what happens when I have 47 things I have to do,
given how lousy my memory is. I miss things.

Update to v102r16 release.
byuu says:
Changelog:
- Emulator::Stream now allows adding low-pass and high-pass filters
dynamically
- also accepts a pass# count; each pass is a second-order biquad
butterworth IIR filter
- Emulator::Stream no longer automatically filters out >20KHz
frequencies for all streams
- FC: added 20Hz high-pass filter; 20KHz low-pass filter
- GB: removed simple 'magic constant' high-pass filter of unknown
cutoff frequency (missed this one in the last WIP)
- GB,SGB,GBC: added 20Hz high-pass filter; 20KHz low-pass filter
- MS,GG,MD/PSG: added 20Hz high-pass filter; 20KHz low-pass filter
- MD: added save state support (but it's completely broken for now;
sorry)
- MD/YM2612: fixed Voice#3 per-operator pitch support (fixes sound
effects in Streets of Rage, etc)
- PCE: added 20Hz high-pass filter; 20KHz low-pass filter
- WS,WSC: added 20Hz high-pass filter; 20KHz low-pass filter
So, the point of the low-pass filters is to remove frequencies above
human hearing. If we don't do this, then resampling will introduce
aliasing that results in sounds that are audible to the human ear. Which
basically an annoying buzzing sound. You'll definitely hear the
improvement from these in games like Mega Man 2 on the NES. Of course,
these already existed before, so this WIP won't sound better than
previous WIPs.
The high-pass filters are a little more complicated. Their main role is
to remove DC bias and help to center the audio stream. I don't
understand how they do this at all, but ... that's what everyone who
knows what they're talking about says, thus ... so be it.
I have set all of the high-pass filters to 20Hz, which is below the
limit of human hearing. Now this is where it gets really interesting ...
technically, some of these systems actually cut off a lot of range. For
instance, the GBA should technically use an 800Hz high-pass filter when
output is done through the system's speakers. But of course, if you plug
in headphones, you can hear the lower frequencies.
Now 800Hz ... you definitely can hear. At that level, nearly all of the
bass is stripped out and the audio is very tinny. Just like the real
system. But for now, I don't want to emulate the audio being crushed
that badly.
I'm sticking with 20Hz everywhere since it won't negatively affect audio
quality. In fact, you should not be able to hear any difference between
this WIP and the previous WIP. But theoretically, DC bias should mostly
be removed as a result of these new filters. It may be that we need to
raise the values on some cores in the future, but I don't want to do
that until we know for certain that we have to.
What I can say is that compared to even older WIPs than r15 ... the
removal of the simple one-pole low-pass and high-pass filters with the
newer three-pass, second-order filters should result in much better
attenuation (less distortion of audible frequencies.) Probably not
enough to be noticeable in a blind test, though.

Update to v102r15 release.
byuu says:
Changelog:
- nall: added DSP::IIR::OnePole (which is a first-order IIR filter)
- FC/APU: removed strong highpass, weak hipass filters (and the
dummied out lowpass filter)
- MS,GG,MD/PSG: removed lowpass filter
- MS,GG,MD/PSG: audio was not being centered properly; removed
centering for now
- MD/YM2612: fixed clipping of accumulator from 18 signed bits to 14
signed bits (-0x2000 to +0x1fff) [Cydrak]
- MD/YM2612: removed lowpass filter
- PCE/PSG: audio was not being centered properly; removed centering
for now
First thing is that I've removed all of the ad-hoc audio filtering.
Emulator::Stream intrinsically provides a three-pass, second-order
biquad IIR butterworth lowpass filter that clips frequencies above 20KHz
with very good attenuation (as good as IIR gets, anyway.)
It doesn't really make sense to have the various cores running
additional lowpass filters. If we want to filter frequencies below
20KHz, then I can adapt Emulator::Audio::createStream() to take a cutoff
frequency value, and we can do it all at once, with much better quality.
Right now, I don't know what frequencies are best to cut off the various
other audio cores, so they're just gone for now.
As for the highpass filters for the Famicom core, well ... you don't get
aliasing from resampling low frequencies. And generally speaking, too
low a frequency will be inaudible anyway. All these were doing was
killing possible bass (if they were too strong.) We can add them again,
but only if someone can convert Ryphecha's ad-hoc magic integers into a
frequency cutoff. In which case, I'll use my biquad IIR filter to do it
even better. On this note, it may prove useful to do this for the MD PSG
as well, to try and head off unnecessary clamping when mixing with the
YM2612.
Finally, there was the audio centering issue that affected the
MS,GG,MD,PCE,SG cores. It was flooring the "silent" audio level, which
was resulting in extremely heavy distortion if you tried listening to
higan and, say, audacious at the same time. Without the botched
centering, this distortion is completely gone now.
However, without any centering, we've halved the potential volume range.
This means the audio slider in higan's audio settings panel will start
clamping twice as quickly. So ultimately, we need to figure out how to
fix the centering. This isn't as simple as just subtracting less. We
will probably have to center every individual audio channel before
summing them to do this properly.
Results:
On the Mega Drive, Altered Beast sounds quite a bit better, a lot less
distortion now. But it's still not perfect, especially sound effects.
Further, Bare Knuckle / Streets of Rage still has really bad sound
effects. It looks like I broke something in Cydrak's code when trying to
adapt it to my style =(

Update to v102r02 release.
byuu says:
Changelog:
- I caved on the `samples[] = {0.0}` thing, but I'm very unhappy about it
- if it's really invalid C++, then GCC needs to stop accepting it
in strict `-std=c++14` mode
- Emulator::Interface::Information::resettable is gone
- Emulator::Interface::reset() is gone
- FC, SFC, MD cores updated to remove soft reset behavior
- split GameBoy::Interface into GameBoyInterface,
GameBoyColorInterface
- split WonderSwan::Interface into WonderSwanInterface,
WonderSwanColorInterface
- PCE: fixed off-by-one scanline error [hex_usr]
- PCE: temporary hack to prevent crashing when VDS is set to < 2
- hiro: Cocoa: removed (u)int(#) constants; converted (u)int(#)
types to (u)int_(#)t types
- icarus: replaced usage of unique with strip instead (so we don't
mess up frameworks on macOS)
- libco: added macOS-specific section marker [Ryphecha]
So ... the major news this time is the removal of the soft reset
behavior. This is a major!! change that results in a 100KiB diff file,
and it's very prone to accidental mistakes!! If anyone is up for
testing, or even better -- looking over the code changes between v102r01
and v102r02 and looking for any issues, please do so. Ideally we'll want
to test every NES mapper type and every SNES coprocessor type by loading
said games and power cycling to make sure the games are all cleanly
resetting. It's too big of a change for me to cover there not being any
issues on my own, but this is truly critical code, so yeah ... please
help if you can.
We technically lose a bit of hardware documentation here. The soft reset
events do all kinds of interesting things in all kinds of different
chips -- or at least they do on the SNES. This is obviously not ideal.
But in the process of removing these portions of code, I found a few
mistakes I had made previously. It simplifies resetting the system state
a lot when not trying to have all the power() functions call the reset()
functions to share partial functionality.
In the future, the goal will be to come up with a way to add back in the
soft reset behavior via keyboard binding as with the Master System core.
What's going to have to happen is that the key binding will have to send
a "reset pulse" to every emulated chip, and those chips are going to
have to act independently to power() instead of reusing functionality.
We'll get there eventually, but there's many things of vastly greater
importance to work on right now, so it'll be a while. The information
isn't lost ... we'll just have to pull it out of v102 when we are ready.
Note that I left the SNES reset vector simulation code in, even though
it's not possible to trigger, for the time being.
Also ... the Super Game Boy core is still disconnected. To be honest, it
totally slipped my mind when I released v102 that it wasn't connected
again yet. This one's going to be pretty tricky to be honest. I'm
thinking about making a third GameBoy::Interface class just for SGB, and
coming up with some way of bypassing platform-> calls when in this
mode.

Update to v100r14 release.
byuu says:
(Windows: compile with -fpermissive to silence an annoying error. I'll
fix it in the next WIP.)
I completely replaced the time management system in higan and overhauled
the scheduler.
Before, processor threads would have "int64 clock"; and there would
be a 1:1 relationship between two threads. When thread A ran for X
cycles, it'd subtract X * B.Frequency from clock; and when thread B ran
for Y cycles, it'd add Y * A.Frequency from clock. This worked well
and allowed perfect precision; but it doesn't work when you have more
complicated relationships: eg the 68K can sync to the Z80 and PSG; the
Z80 to the 68K and PSG; so the PSG needs two counters.
The new system instead uses a "uint64 clock" variable that represents
time in attoseconds. Every time the scheduler exits, it subtracts
the smallest clock count from all threads, to prevent an overflow
scenario. The only real downside is that rounding errors mean that
roughly every 20 minutes, we have a rounding error of one clock cycle
(one 20,000,000th of a second.) However, this only applies to systems
with multiple oscillators, like the SNES. And when you're in that
situation ... there's no such thing as a perfect oscillator anyway. A
real SNES will be thousands of times less out of spec than 1hz per 20
minutes.
The advantages are pretty immense. First, we obviously can now support
more complex relationships between threads. Second, we can build a
much more abstracted scheduler. All of libco is now abstracted away
completely, which may permit a state-machine / coroutine version of
Thread in the future. We've basically gone from this:
auto SMP::step(uint clocks) -> void {
clock += clocks * (uint64)cpu.frequency;
dsp.clock -= clocks;
if(dsp.clock < 0 && !scheduler.synchronizing()) co_switch(dsp.thread);
if(clock >= 0 && !scheduler.synchronizing()) co_switch(cpu.thread);
}
To this:
auto SMP::step(uint clocks) -> void {
Thread::step(clocks);
synchronize(dsp);
synchronize(cpu);
}
As you can see, we don't have to do multiple clock adjustments anymore.
This is a huge win for the SNES CPU that had to update the SMP, DSP, all
peripherals and all coprocessors. Likewise, we don't have to synchronize
all coprocessors when one runs, now we can just synchronize the active
one to the CPU.
Third, when changing the frequencies of threads (think SGB speed setting
modes, GBC double-speed mode, etc), it no longer causes the "int64
clock" value to be erroneous.
Fourth, this results in a fairly decent speedup, mostly across the
board. Aside from the GBA being mostly a wash (for unknown reasons),
it's about an 8% - 12% speedup in every other emulation core.
Now, all of this said ... this was an unbelievably massive change, so
... you know what that means >_> If anyone can help test all types of
SNES coprocessors, and some other system games, it'd be appreciated.
----
Lastly, we have a bitchin' new about screen. It unfortunately adds
~200KiB onto the binary size, because the PNG->C++ header file
transformation doesn't compress very well, and I want to keep the
original resource files in with the higan archive. I might try some
things to work around this file size increase in the future, but for now
... yeah, slightly larger archive sizes, sorry.
The logo's a bit busted on Windows (the Label control's background
transparency and alignment settings aren't working), but works well on
GTK. I'll have to fix Windows before the next official release. For now,
look on my Twitter feed if you want to see what it's supposed to look
like.
----
EDIT: forgot about ICD2::Enter. It's doing some weird inverse
run-to-save thing that I need to implement support for somehow. So, save
states on the SGB core probably won't work with this WIP.

Update to v099r11 release.
byuu says: Changelog: - NES PPU core updated to use BitFields (absolutely massive improvement in code readability) - NES APU core updated to new coding style - NES cartridge/board and cartridge/chip updated to new coding style - pushed NES PPU rendering one dot forward (doesn't fix King's Quest V yet, sadly) - fixed SNES PPU BG tilemask for 128KiB VRAM mode (doesn't fix Yoshi's Island, though) So ... I kind of went overboard with the fc/cartridge changes. This WIP diff is 185KiB >_> I didn't realize it was going to be as big a task as it was, but once I started everything broke in a chain reaction, so I had to do it all at once. There's a massive chance we've broken a bunch of NES things. Any typos in this WIP are going to be absolutely insidious to track down =( But ... supposing I pulled it off, this means the Famicom core is now fully converted to the new coding style as well. That leaves only the GB and GBA cores. Once those are finished, then we'll finally be free of these gigantic hellspawn diffs. |

Update to v099r04 release.
byuu says: Changelog: - lots of code cleanups to processor/r6502 (the switch.cpp file is only halfway done ...) - lots of code cleanups to fc/cpu - removed fc/input - implemented fc/controller hex_usr, you may not like this, but I want to keep the controller port and expansion port interface separate, like I do with the SNES. I realize the NES' is used more for controllers, and the SNES' more for hardware expansions, but ... they're not compatible pinouts and you can't really connect one to the other. Right now, I've only implemented the controller portion. I'll have to get to the peripheral portion later. Also, the gamepad implementation there now may be wrong. It's based off the Super Famicom version obviously. I'm not sure if the Famicom has different behavior with latching $4016 writes, or not. But, it works in Mega Man II, so it's a start. Everyone, be sure to remap your controls, and then set port 1 -> gamepad after loading your first Famicom game with the new WIP. |

Update to v098r14 release.
byuu says:
Changelog:
- improved attenuation of biquad filter by computing butterworth Q
coefficients correctly (instead of using the same constant)
- adding 1e-25 to each input sample into the biquad filters to try and
prevent denormalization
- updated normalization from [0.0 to 1.0] to [-1.0 to +1.0]; volume/reverb
happen in floating-point mode now
- good amount of work to make the base Emulator::Audio support any number
of output channels
- so that we don't have to do separate work on left/right channels;
and can instead share the code for each channel
- Emulator::Interface::audioSample(int16 left, int16 right); changed to:
- Emulator::Interface::audioSample(double* samples, uint channels);
- samples are normalized [-1.0 to +1.0]
- for now at least, channels will be the value given to
Emulator::Audio::reset()
- fixed GUI crash on startup when audio driver is set to None
I'm probably going to be updating ruby to accept normalized doubles as
well; but I'm not sure if I will try and support anything other 2-channel
audio output. It'll depend on how easy it is to do so; perhaps it'll be
a per-driver setting.
The denormalization thing is fierce. If that happens, it drops the
emulator framerate from 220fps to about 20fps for Game Boy emulation. And
that happens basically whenever audio output is silent. I'm probably
also going to make a nall/denormal.hpp file at some point with
platform-specific functionality to set the CPU state to "denormals as
zero" where applicable. I'll still add the 1e-25 offset (inaudible)
as another fallback.

Update to v098r07 release.
byuu says: Changelog: - GB: support modeSelect and RAM for MBC1M (Momotarou Collection) - audio: implemented native resampling support into Emulator::Stream - audio: removed nall::DSP completely Unfortunately, the new resampler didn't turn out quite as fast as I had hoped. The final hermite resampling added some overhead; and I had to bump up the kernel count to 500 from 400 to get the buzzing to go away on my main PC. I think that's due to it running at 48000hz output instead of 44100hz output, maybe? Compared to Ryphecha's: (NES) Mega Man 2: 167fps -> 166fps (GB) Mega Man II: 224fps -> 200fps (WSC) Riviera: 143fps -> 151fps Odd that the WS/WSC ends up faster while the DMG/CGB ends up slower. But this knocks 922 lines down to 146 lines. The only files left in all of higan not written (or rewritten) by me are ruby/xaudio2.h and libco/ppc.c |

Update to v098r06 release.
byuu says:
Changelog:
- emulation cores now refresh video from host thread instead of
cothreads (fix AMD crash)
- SFC: fixed another bug with leap year months in SharpRTC emulation
- SFC: cleaned up camelCase on function names for
armdsp,epsonrtc,hitachidsp,mcc,nss,sharprtc classes
- GB: added MBC1M emulation (requires manually setting mapper=MBC1M in
manifest.bml for now, sorry)
- audio: implemented Emulator::Audio mixer and effects processor
- audio: implemented Emulator::Stream interface
- it is now possible to have more than two audio streams: eg SNES
+ SGB + MSU1 + Voicer-Kun (eventually)
- audio: added reverb delay + reverb level settings; exposed balance
configuration in UI
- video: reworked palette generation to re-enable saturation, gamma,
luminance adjustments
- higan/emulator.cpp is gone since there was nothing left in it
I know you guys are going to say the color adjust/balance/reverb stuff
is pointless. And indeed it mostly is. But I like the idea of allowing
some fun special effects and configurability that isn't system-wide.
Note: there seems to be some kind of added audio lag in the SGB
emulation now, and I don't really understand why. The code should be
effectively identical to what I had before. The only main thing is that
I'm sampling things to 48000hz instead of 32040hz before mixing. There's
no point where I'm intentionally introducing added latency though. I'm
kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be
much appreciated :/
I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as
well, and that would be very bad.

Update to v097r13 release.
byuu says: I refactored my schedulers. Added about ten lines to each scheduler, and removed about 100 lines of calling into internal state in the scheduler for the FC,SFC cores and about 30-40 lines for the other cores. All of its state is now private. Also reworked all of the entry points to static auto Enter() and auto main(). Where Enter() handles all the synchronization stuff, and main() doesn't need the while(true); loop forcing another layer of indentation everywhere. Took a few hours to do, but totally worth it. I'm surprised I didn't do this sooner. Also updated icarus gmake install rule to copy over the database. |

It's a boring WIP, I just wanted to push out the project structure change now at the start of this WIP cycle. |

Update to v093 release.
byuu says: Changelog: - added Cocoa target: higan can now be compiled for OS X Lion [Cydrak, byuu] - SNES/accuracy profile hires color blending improvements - fixes Marvelous text [AWJ] - fixed a slight bug in SNES/SA-1 VBR support caused by a typo - added support for multi-pass shaders that can load external textures (requires OpenGL 3.2+) - added game library path (used by ananke->Import Game) to Settings->Advanced - system profiles, shaders and cheats database can be stored in "all users" shared folders now (eg /usr/share on Linux) - all configuration files are in BML format now, instead of XML (much easier to read and edit this way) - main window supports drag-and-drop of game folders (but not game files / ZIP archives) - audio buffer clears when entering a modal loop on Windows (prevents audio repetition with DirectSound driver) - a substantial amount of code clean-up (probably the biggest refactoring to date) One highly desired target for this release was to default to the optimal drivers instead of the safest drivers, but because AMD drivers don't seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD has too big a market share. Hopefully with v093 officially released, we can get some public input on what AMD doesn't like. |

Update to v092r09 release.
byuu says:
This will be another massive diff from the previous version.
All of higan was updated to use the new foo& bar syntax, and I also
updated switch statements to be consistent as well (but not in the
disassemblers, was starting to get an RSI just from what I already did.)
phoenix/{windows, cocoa, qt} need to be updated to use "string foo"
instead of "const string& foo", and after that, the major diffs should
be finished.
This archive is the first time I'm posting my copy-on-write,
size+capacity nall::string class, so any feedback on that is welcome as
well.

Update to higan v091 release.
byuu says: Basically just a project rename, with s/bsnes/higan and the new icon from lowkee added in. It won't compile on Windows because I forgot to update the resource.rc file, and a path transform command isn't working on Windows. It was really just meant as a starting point, so that v091 WIPs can flow starting from .00 with the new name (it overshadows bsnes v091, so publicly speaking this "shouldn't exist" and will probably be deleted from Google Code when v092 is ready.) |
